Coniferous Forest

This page explores the the life and climate in the coniferous forest (tiaga). It explains the species of plants, animals and the adverage climate. This is just some of the interesting information on this page.


There are many varieties of animals in the coniferous forest. It consists of many types of rodents, birds and predators. Starting with the rodents, there are many types of squirrels like the brown and grey squirrel. There are also oppossums and racoons. At the top of the food chain are wolves, bears and mountain lions. These animals have the fewest number because of lack of food. They also keep the food chain in balance.

The rodents in the coniferous forest are the next in line in the food chain. They prey on mainly small animals or vegetation. They are small mammals that mostly come out at night.

The birds are the most interesting of all because they come in large and small sizes and they are predators and herbivores. The American bald eagle is one of the few predators; it preys on small rodents like mice. Another predator is the bluejay which feeds on worms and bugs.


Most trees in the coniferous forest are evergreens which means that they keep their needles year round. Most trees keep their needles for two to three years but the spruce tree can keep its needles for up to 15 years! They keep their needles to help keep them warm in the winter and cool in the summer. Conifers are cone shaped to accommodate large amounts of snowfall in the winter.

The reason that these trees are some of the few species of trees that grow here are because of the harsh weather conditions.


The climate in the coniferous forest is charaterized by strong seasonal variations with short moderately warm and moist summers and long, extremely cold and dry winters. The temperature range is extreme. Seasonal fluctuation can be as great as 100 degrees F. The climate controls are altitude, geographic location, and latitude, and heating of land. The average rainfall in the coniferous forest is about 9.4 inches per month.
